Colors of the Rainbow Cards
From In-Print For Children
Children stack three primary color overlay cards (one at a time) on top of the base card to build a seven-color spectrum. There is much to notice as the colors blend. What happens to the band labeled orange when the red overlay is placed? Why is there no green arc until the yellow overlay is placed?
Includes sturdy base card and 3 transparent plastic color overlay cards, plus a resource page with scientific explanation and two experiments for separating white light into colors. Made in U.S.A.
6" x 4¾".
